在 Swift 中更改 UITextView 的 textColor

Question

I have an iOS project I'm working on using Xcode7 and Swift2 . I have a UITextView that I'm trying to change the textColor of. It has a black background color.

I looked here and could not find a setTextColor . I also tried below in the UIViewController of where the UITextView is located with no luck:

@IBOutlet weak var codeText: UITextView!
override func viewDidLoad() {
    super.viewDidLoad()

    self.codeText.delegate = self

    codeText.textColor = UIColor.whiteColor()
}

I then went into the Inspector and tried clicking on the UITextView and changing the textColor there with no luck of it changing. Am I doing something wrong?

Thank you.

Answer 1

on your ViewController remove the line

self.codeText.delegate = self

You can not assign a value of type "ViewController" to type "UITextViewDelegate?"

codeText.textColor = UIColor.redColor()

works just fine.

Answer 2

You are sure that your codeText variale is not nil? in my opinion your code should work. Please check wether codeText is not nil.

Answer 3

I ended up deleting the UITextField in the Storyboard and putting a new one. I connected it to the ViewController with an @IBOutlet as before. I then went to 'Product' and 'Clean'. Afterwards I ran my my project and it worked fine. I still had the newly added UITextView called codeText assigned to the UITextFieldDelegate and works beautifully. Must have just had a bug in it and needed to start fresh.

你需要用 .foregroundColor: UIColor.label 添加 NSAttributedString
